Valve Cover Breather 10mm Inlet Black/Chrome

The Valve Cover Breather 10mm Inlet Black/Chrome (Model 43510) from Edelbrock is a precision-engineered crankcase ventilation component designed for high-performance and street applications. This clamp-on breather serves a critical function in engine management by allowing controlled relief of crankcase pressure and vapors, preventing seal degradation and maintaining engine longevity. Whether you're building a classic muscle car, restoring a vintage truck, or optimizing a performance platform, this 10mm inlet breather delivers reliable, maintenance-free operation in demanding conditions.

Manufactured from durable steel construction with a professional black and chrome finish, the Valve Cover Breather 10mm Inlet features a conical design that maximizes flow efficiency while minimizing turbulence. The 10mm outer diameter tube inlet accommodates standard breather hose connections, and the reusable filtration system reduces maintenance intervals compared to disposable alternatives. Edelbrock's engineering ensures consistent baffle performance across temperature and pressure variables, protecting your engine from moisture and contaminant ingress while maintaining optimal crankcase ventilation rates.

Technicians and engine builders rely on this breather for carbureted and fuel-injected platforms where OEM solutions fall short. Installation is straightforward—the clamp-on design secures directly to valve covers without drilling or permanent modifications, making it ideal for rapid prototyping or restoration work. Compact dimensions (4.1 x 2.1 x 6.05 inches) allow flexible mounting in tight engine bays, and the modest 0.16 lb weight eliminates any concern for weight distribution or balance. Compatible with most domestic V-8 and small-block applications using 10mm hose connections, this breather pairs seamlessly with custom intake manifolds, headers, and carbureted systems.
